down. Figure 17 shows a countup sequence followed
by a countdown sequence, both across the zero posi-

DIR-INC Mode
In DIR-INC mode a change in angle for both directions
of rotation generates an output pulse for signal CLK
(pin A). Signal DIR (pin B) gives the direction of ro- ^NCLR
tation. This mode permits the operation of external
binary counter modules (such as 74HC/HCT191, for
example), with signal NCLR (pin C) being used to re-
set the external counter. With a rising edge at CLK
the counter status is counted up or down, depending
on the value of the DIR signal. A low level at DIR trig-
